Bernabei D., Hakke-Patil A., Banterle F., Di Benedetto M., Ganovelli F., Pattanaik S., Scopigno R. A parallel architecture for interactively rendering scattering and refraction effects. In: IEEE Computer Graphics and Applications, vol. 32 (2) pp. 34 - 43. IEEE, 2012.
A new method for interactive rendering of complex lighting effects combines two algorithms. The first performs accurate ray tracing in heterogeneous refractive media to compute high-frequency phenomena. The second applies lattice-Boltzmann lighting to account for low-frequency multiple-scattering effects. The two algorithms execute in parallel on modern graphics hardware. This article includes a video animation of the authors' real-time algorithm rendering a variety of scenes
